How to generate a sqlite3-compatible dump from Propel's schema.xml - sqlite

Question

To speed up the unit tests I want to use SQLite instead of MySQL, so I'm trying to get a SQLite-compatible dump of the databases from Propel's schema.xml. The application is built in Symfony2, and this is how the db configuration in config.yml looks like:
propel:
dbal:
driver: sqlite
dsn: sqlite:/tmp/test_db1.sq3
default_connection: db1
connections:
db1:
user: %database_user%
password: %database_password%
dsn: sqlite:/tmp/test_db1.sq3
db2:
user: %database_user%
password: %database_password%
dsn: sqlite:/tmp/test_db2.sq
However, the command app/console propel:build-sql is always generating MySQL-specific dumps that fail to load into SQLite.
I've also removed any references to MySQL from properties.ini and still don't get it right.
Any ideas?

Each connection name has to be related to a database name, so if you declare a connection c1, you need to have a database tag with the attribute name="c1" (in your schema.xml).
Assuming you have the following schema.xml:
<database name="default">
…
</database>
Write the following section in your config.yml:
propel:
dbal:
default_connection: default
connections:
default:
driver: mysql
username: root
dsn: mysql:host=localhost;dbname=my_db
And the following definition in config_test.yml:
propel:
dbal:
connections:
default:
driver: sqlite
dsn: sqlite:/tmp/test_db1.sq3
Then, if you want to generate SQL statements for your tests, just run:
php app/console --env=test propel:build-sql
To generate SQL statements for your dev env:
php app/console propel:build-sql
or
php app/console --env=dev propel:build-sql
